In the US, there's been 172k death in half a year for Covid. And if using the worst case data for flu season, it's 61k per year. So it's looking like for a full year, it'll be 344k death for Covid versus 61k death for the flu.
That makes Covid 5.6 times more deadly than the flu.
But, the Covid numbers here are from a complete lockdown, where people are social distancing, wearing masks, schools are closed, everyone is working from home if possible, etc. And even with those level of precautions, it is at best 5.6 times deadlier.
That's why the estimate from the CDC is that Covid is 10 times deadlier than the flu.
The other thing is, this only measures immediate death. But there are unknown long term risk. Other type of SARS virus are known to cause long term issues to people that recovered from it. Hopefully this doesn't turn out to be the case for Covid but it could, and we don't know yet.
The last problem is mutations are possible. There's already one known mutation that makes it even more contagious. And the more the virus spreads, the more likely it mutates as well. So containment is important for that as well.
Now, that's the risk of it from the data today. You can decide that it is a risk worth taking or not. That's kind of a personal thing. But it is absolutely much higher than the flu.
